Wide Hookless Bead Flat Protection

GOODBYE TO PINCH FLATS

ENVE Wide Hookless Bead technology is found exclusively in the M Series 525, 630, 635, and 640 model wheels where weight savings is valued over ultimate high impact and pinch flat durability.

As carbon rims have become hookless and increasingly more durable, we have transitioned from rim failures to tire failures. Wearing a tire tread down to the casing is a thing of the past as most tires are lucky if they survive 50 miles of aggressive riding over obstacle laden terrain. While destroying an expensive tire on a weekly basis isnt affordable, its a complete interruption of flow, and an utter buzzkill with a flat tire, regulated to the side of the trail.

ENVEs wide hookless bead is the result of 2 years of carbon mountain bike rim development to address this above scenario. The result is a rim shape that features a wider leading edge of the hookless bead. This broad surface creates a more forgiving platform on which the tire can bottom out, and proves extremely effective in reducing the likelihood of "pinch" or "snake-bite" style flat.

In addition to greatly improving tire performance and reliability, the wide hookless bead design beefs up the leading edge of the rim and allows for greater impact resistance.

ENVE Wide Hookless Bead (Patent Pending) delivers:

• 60% improvement in pinch flat resistance over other hookless rims
• Ability to run lower tire pressure and improve traction and rolling resistance
• The option to run lighter weight tires if desired
• A more forgiving buffer between rim and trail
• Greater impact resistance

Tuned Carbon Fiber Construction

PERFECT RIDE FEEL FOR EVERY DISCIPLINE

Each rim and wheel model in the ENVE M Series is specifically designed for a refined application specific ride experience.

Paying tribute to the original M Series, the M5, M6, M7, and M9 Series follow the original M Series descent to climb ratios that are used to help you the rider align your ride preferences with the appropriate M Series wheel for you.

We tune each M series wheel model to the intended application by tuning everything from hole count to the very carbon laminate used to create the rims structure.

Smart Spoke Count

MORE DURABLE, LIGHTER WEIGHT

Just as one rim doesnt serve all applications equally, the same goes for the actual number of spokes required to optimize the ride quality and experience. As such, the M525, a rim specifically designed for XC racing on short travel bikes features 24 spoke holes which saves notable weight and adds compliance for long hours in the saddle. On the other end of the spectrum the 32 spoke hole M9 Series and M7 Series wheels need to survive repeated intervals of descending down technical terrain at sensory numbing speeds. In the middle, the M6 Series wheels feature a 28-hole count.

ENVEs patented Molded Spoke Hole Technology offers a variety of benefits that ultimately result in a more durable and reliable carbon fiber rim and wheel. Visit Why ENVE for more details.

Unidirectional Raw Material

PERFORMANCE THROUGH THE BEST MATERIALS

At ENVE, we use only the best materials in the construction of our rims. In this case, 100% unidirectional carbon fiber. Over the years we have developed and identified specific construction methods, resin systems, and manufacturing techniques that best serve the mountain application.

The result is that each rim in the M Series, while sharing in pedigree, has a dedicated laminate to ensure the best on-trail performance. As an example, the forces inflicted upon a wheelset by a trail rider on a 130mm bike are very different than the forces exerted on a wheelset used for downhill racing on a 200mm bike. Therefore, the laminate is optimized to create a structure that achieves the desired impact resistance, stiffness, and compliance.
